All week long, you've voted for the top headlines in our Best of Summer: Biggest News Stories tournament and we're now down to the final round. The last two defining stories of summer that are left are the 2014 World Cup (and everyone's obsession with soccer for weeks) and the news of Robin Williams' tragic death at age 63. Both stories are big deals for obvious and different reasons.

So which one do you think defines the summer of 2014? Vote in found four of our tournament and come back Friday to see who wins.
